Hysteresis, Avalanches, and Noise: Numerical Methods
Matthew C. Kuntz, Olga Perkovic, Karin A. Dahmen +2
In studying the avalanches and noise in a model of hysteresis loops we have developed two relatively straightforward algorithms which have allowed us to study large systems efficie…
Defect--Defect Correlation Functions, Generic Scale Invariance, and the Complex Ginzburg--Landau Equation
Bruce W. Roberts, Eberhard Bodenschatz, James P. Sethna
Motivated by the idea of developing a ``hydrodynamic'' description of spatiotemporal chaos, we have investigated the defect--defect correlation functions in the defect turbulence r…
Defect--Defect Correlation Functions, Generic Scale Invariance, and the Complex Ginzburg--Landau Equation
Bruce W. Roberts, Eberhard Bodenschatz, James P. Sethna
We present a calculation of defect--defect correlation functions in the defect turbulence regime of the complex Ginzburg--Landau equation. Our results do not agree with the predict…
Hysteresis and hierarchies: dynamics of disorder-driven first-order phase transformations
James P. Sethna, Karin Dahmen, Sivan Kartha +3
We use the zero-temperature random-field Ising model to study hysteretic behavior at first-order phase transitions. Sweeping the external field through zero, the model exhibits hys…
